adj.雙棱錐

A trigonal bipyramid has three equatorial and two axial positions. 一個(gè)三角雙錐體有三個(gè)赤道位和兩個(gè)軸向位。

The structure shows a distorted trigonal bipyramidal configuration with five-coordinations to a central tin atom. 結(jié)果表明,化合物中錫原子呈五配位畸變?nèi)请p錐構(gòu)型。

Diamond crystats are intermediate between dihydrate and monohydrate calcium oxalate,two crystal forms:pyramide and bipyramid,therefore,it is not dihydrate calcium oxalate. 本研究發(fā)現(xiàn)菱形晶屬于一水和二水草酸鈣的中問晶體,菱形晶有兩種晶體形式,單錐和雙錐的結(jié)晶形式,菱形晶不是二水草酸鈣。

The crystal structure has been determined by X ray single crystal diffraction, showing a distorted trigonal bipyramidal configuration with five coordination for the central tin atom. 通過元素分析、紅外光譜和氫核磁共振譜對(duì)其結(jié)構(gòu)進(jìn)行了表征。用X-射線單晶衍射測定了該化合物的晶體結(jié)構(gòu)。

The result shows that the mix of W+C prepared by the the bipyramid blender has high chemical carbon?less the Fe content . the bond strength of WC block is small and the proudtion efficiency is high. 結(jié)果表明雙錐混合器生產(chǎn)效率高、碳化鎢粘結(jié)度低、化合碳也高,完全可以替代用球磨機(jī)配碳的傳統(tǒng)工藝。
